Ultra-pure Viscoelastic Damping Polymers are designed to be used in damping applications as part of a constrained
layer damper or damped laminate designs.
1. Surface Preparation - Use cleaning solvents like isopropyl alcohol or heptane to make sure the application surface is
dry and free of any wax, grease, dust, dirt, oil, scale or any other contaminants or loose or weakly attached surface finishes
or coatings. More aggressive solvents may be needed to remove contaminants.
or coatings. More aggressive solvents may be needed to remove contaminants.
2. Surface Type - The 3M ultra-pure viscoelastic damping polymer will form good bonds when properly applied to many
high surface energy materials. Materials with a surface energy below 100 dynes/cm
2
should be tested to determine if a
suitable development of an adequate bond for a given end use application will occur.
3. Application - The 3M ultra-pure viscoelastic damping polymer is tacky at room temperature (21ºC). The 3M polymer
requires only rolling or squeegeeing methods to apply pressure to the 3M polymer to make an adequate bond to a
contamination free surface. Air entrapment should be avoided to ensure a good bond.
contamination free surface. Air entrapment should be avoided to ensure a good bond.
A good method is to first attach one edge of the damper with it’s liner removed to the substrate, then gradually lower the
damper or damping polymer onto the surface at an angle of (30-90º) while continually applying uniform pressure to the
damping polymer of 10-15 psi (6.9-10.3 pascals). Maintain uniform pressure across a wide area. Every effort should be
made to avoid air entrapment while placing the damping polymer onto the flexible circuit substrate.
